Sir John Cuninghame has had wide experience as an investment banker and venture capitalist both in North America and in Europe. Sir John claims the title of Earl of Glencairn although he has never officially petitioned the House of Lords. His ancestors did not petition for the title in the House of Lords in 1797 as they had not provided sufficient evidence of being heirs-male to the Earls of Glencairn and again were denied in the 19th century due to a lack of propinquity.
